ASUS SABERTOOTH z77 CMOS BATTERY REPLACEMENT

Hello everyone, I had a problem with my PC, when turned on it would only get to a screen with American Megatrends, some white BIOS text and would not go any further until I went into the BIOS to run set up every time I turned on the PC. The info at the American Megatrends screen would also vary with the type of info displayed, mainly with the SATA Port info missing some Ports. When I got into the BIOS the Date and Time was also wrong, always defaulting to 1/1/2009, even though I changed it every time. I researched online and the most common answer was that the CMOS Battery on the Motherboard was dying and not holding it&charge, so all the BIOS settings like Time, Date and custom settings were not saving when you turned off your PC....although, another number of thoughts mentioned that could also be the cause was...Power Supply developing a fault, SATA Cables becoming loose in the Motherboard connectors,, Motherboard Connectors themselves becoming sloppy or the actual SATA cables becoming faulty...I tried all of these but still got the same problem, so the CMOS battery replacement it is then. The Asus Sabertooth z77 Thermal Armor, while looking good and possibly does what it is supposed to do ....is a pain when it comes to changing out the CMOS Battery...having to disconnect and take out most of the items connected to the Motherboard was annoying, to say the least. I was very lucky that the CPU Liquid cooler Radiator Fan unit that was installed on the CPU slipped through...
